Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 48/788,56/711
Formula to find GCF of Fractions is
GCF = GCF of Numerators/LCM of Denominators
As per the formula GCF of Fractions let’s split into two parts and find the GCF of Numerators and LCM of Denominators
In the given fractions GCF of Numerators means GCF of 48,56
Greatest Common Factor of Numerators i.e. GCF of 48,56 is 8 .
LCM of Denominators means LCM of 788,711 as per the given fractions.
LCM of 788,711 is 560268 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 48,56
2 | 48, 56 |
2 | 24, 28 |
2 | 12, 14 |
6, 7 |
∴ So the GCF of the given numbers is 2 x 2 x 2 = 8
Factors of 48
List of positive integer factors of 48 that divides 48 without a remainder.
1,2,3,4,6,8,12,16,24,48
Factors of 56
List of positive integer factors of 56 that divides 56 without a remainder.
1,2,4,7,8,14,28,56
Greatest Common Factor
We found the factors 48,56 . The biggest common factor number is the GCF number.
So the greatest common factor 48,56 is 8.
Lets's calculate LCM of 788,711
Given numbers has no common factors except 1. So, there LCM is their product i.e 560268
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 8/560268
Therefore, the GCF of Fractions 48/788,56/711 is 8/560268
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 788,711 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(788,711) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(788,711) x common factors =1 x 1 = 1
LCM(788,711) = ( 788 × 711 ) / 1
LCM(788,711) = 560268 / 1
LCM(788,711) = 560268
